Image slider

I tried to change the size of the ARI image slider on the front page. I wanted to change the height of the module but even I gave the new height it didn't change on the front page. So i downloaded the latest ARI Image slider and updated it on my site. Now the image is pretty messed up and I still can't change the height of the image. What should I do to change it?

I attach a preview image.

Thank you,
Mark

Do you have a live site? If yes please send backend super admin acces by email (destek@joomlatema.net) I will check it.
